The vapor chamber includes a housing, a capillary structure, at least two liquid-filling and gas-discharging pipes and a working fluid; the housing has a bottom housing plate and a top housing plate correspondingly engaged and sealed with the bottom housing plate, and a single chamber is formed between the top housing plate and the bottom housing plate; the capillary structure is disposed in the single chamber; each of the liquid-filling and gas-discharging pipes is allowed to penetrate into the housing and communicate with the single chamber; and the working fluid is disposed in the single chamber. Accordingly, the working fluid can be evenly and widely distributed in the single chamber.
Description
The present invention relates to a heat dissipation technology, specifically to a vapor chamber and a manufacturing method thereof.
With the currently increasing calculation speeds of electronic components, the heat generated by electronic components are also increasing as a result. To effectively solve the problems caused by high heat, people skilled in the art have already been using a vapor chamber with excellent thermal conductivity to dissipate the heat. However, the conventional vapor chamber still has many disadvantages, including poor thermal conducting performance, high production costs and manufacturing difficulty, which all need to be improved.
The conventional vapor chamber mainly includes a top housing member and a bottom housing member, and a capillary tissue disposed in an internal space defined at the inner sides of the top housing member and the bottom housing member. The top housing member and the bottom housing member are correspondingly engaged with a soldering means, and a working fluid is filled inside the top housing member and the bottom housing member. Lastly, a gas discharging and sealing operation is processed to finish the assembly.
Because the means of generating heat sources of electronic components vary with further developments in technology, the shape of the vapor chamber applied in the above-mentioned heat source has to be correspondingly changed, and the amount of working fluid affects the quantity of limited space for the phase changes of vaporizing and liquidizing. In other words, an excessive amount of the working fluid would greatly reduce the vaporizing space, and an inadequate amount of the working fluid would cause an internal idle burning situation. As such, for a conventional vapor chamber with a larger contact surface area or a certain shape, the filled working fluid cannot be evenly and widely distributed in an internal space of each housing causing poor thermal conductivity and poor heat dissipation.
Accordingly, the applicant of the present invention has devoted himself to improving the mentioned disadvantages.
The present invention is to provide a vapor chamber and a manufacturing method thereof, which has an advantage of allowing a working fluid to be evenly and widely distributed in single chamber with an installation of each liquid-filling and gas-discharging pipe.
Accordingly, the present invention provides a vapor chamber, which includes a housing, a capillary structure, at least two liquid-filling and gas-discharging pipes and a working fluid; the housing has a bottom housing plate and a top housing plate correspondingly engaged and sealed with the bottom housing plate, and a single chamber is formed between the top housing plate and the bottom housing plate; the capillary structure is disposed in the single chamber; each of the liquid-filling and gas-discharging pipes is allowed to penetrate into the housing and communicate with the single chamber; and the working fluid is disposed in the single chamber.
Accordingly, the present invention provides a manufacturing method of a vapor chamber, which includes steps of: a) providing a housing having a single chamber and at least two liquid-filling and gas-discharging pipes; b) providing a working fluid to be filled into the single chamber via each of the liquid-filling and gas-discharging pipes; c) processing a heating operation to the housing for allowing gas inside the single chamber to be discharged via each of the liquid-filling and gas-discharging pipes; and d) processing an edge sealing operation to each of the liquid-filling and gas-discharging pipes after the step c).
In comparison with related art, the present invention has advantageous features as follows. Because the working fluid is evenly distributed, the thermal conducting and the heat dissipating performance of the vapor chamber can be increased. With each of the liquid-filling and gas-discharging pipes being evenly arranged, the working fluid can be more easily filled, thereby allowing the manufacturing process to be simplified.
